According to the bar chart, it is obvious that the number of songs increases as time go by. The music industry became much more productive since the new millennium. Also, there is a huge song population boom in the year 2006 and 2007, taking up almost 50 percent of the total amount. Readers interested can dig in to find out what happened that year causing such significant increase.
Clearly, the Rock music takes up most of the positions in the music world over 50 percent, following by Pop, Metal, and country music.
We can see that the Rock music sticks at the top in the past decades. However, since the 90s, Pop music starts to grow really fast and become the second most popular genre in nowadays. What’s worth mentioning, the metal music was prosperous in the first decade of the new millennium, which may reflect some culture phenomenon behind this.
Seems “You’re”, “love”, “time”, “baby” are the most popular words in all songs. “You’re love, you’re baby through life time.” Is that what the singers want to tell us most, haha.
Most certainly, Hip-Hop songs have the most words, over 500 hundred per song on averge while the rest are pretty much the same. In the boxplot, we can see that even though Hip-Hop song has the highest mean, the maximum of words comes from Rock music, over 6000 words! And the data in this group is highly skewed as well.
“Time”, “life”, “world”, “die”, interesting. Seems Metal has more than just one layer of love. “God”, “death”, “heart”, we cam see Metal is a more spiritial genre.
Aha, here comes our most edgy subject, better mind your language, sir.
We can see that Hip-Hop and Metal have more negative words than positive ones while electronic music is the oppsite.

We have to admit, “love” is an eteral topic through time. It’s even above time itself!
We can see from the chart that the changes in numbers of popular words is comsistent with the song population, indaicating that authors compose in a regular fashion no significant style changing in lyric writtings.
From this study, we find out several fun facts about modern songs and lyrics.

Among all genres, the Rock music takes up the most positions in the music world, while the Pop music starts to prosperous since 90s and becomes the second most popular genre nowadays.
Then, in the lyrics level, we realize that normally Hip-Hop songs have significantly more words than the others and the word count distribution of Rock music is highly skewed indicating that Rock music has very flexible styles.
Last but not least, “love” is the most popular and last-forever word or topic in the music world. However, it never lacks of diversity in the world: Metal music focus more on spiritual topics while the Hip-Hop music probably have some “bad language” issues.
